Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What will be the resulting RNA from this DNA sequence:GAT-TAC?
A
CTA-ATG
B
GAU-UAG
C
CUA-AUG
D
CAT-ACA
Explanation: 

Detailed explanation-1: -This leads to a total of 10 codons in the mRNA sequence AUGGCAGUGCCA as AUG, UGG, GGC, GCA, CAG, AGU, GUG, UGC, GCC, CCA.

Detailed explanation-2: -Description. SeqRNA = dna2rna( SeqDNA ) converts a DNA sequence to an RNA sequence by converting any thymine nucleotides ( T ) in the DNA sequence to uracil nucleotides ( U ). The RNA sequence is returned in the same format as the DNA sequence. For example, if SeqDNA is a vector of integers, then so is SeqRNA .

Detailed explanation-3: -Figure 1: In mRNA, three-nucleotide units called codons dictate a particular amino acid. For example, AUG codes for the amino acid methionine (beige). The idea of codons was first proposed by Francis Crick and his colleagues in 1961.
